Rules of the Road Question 350 diagram
A "I intend to hold course and speed."
B "I intend to pass on your starboard side."
C "I intend to leave you on my port side."
D "I am altering my course to starboard."
AI Explanation

The correct answer is C) "I intend to leave you on my port side." This is the correct answer because under the Inland Navigation Rules, when two power-driven vessels are meeting head-on in an "inland only" situation, one short blast from either vessel indicates that the vessel intends to pass the other vessel on its port side. This allows both vessels to safely pass each other by maintaining their respective courses. The other answer choices are incorrect because: A) does not specifically indicate the intended passing arrangement, B) would indicate passing on the starboard side, and D) would indicate altering course to starboard, which is the opposite of the intended action signaled by one short blast.
